SHARE

Microfine Cement (SuperFine) is an ultrafine blast furnace slag-based cement designed for specialty grouting applications. With a D95 particle size of 10 microns and a D50 particle size of 3 microns, it enables deep penetration into fine soil pores and microscopic rock fissures. This improves ground strength, reduces permeability, and enhances the effectiveness of water cut-off and consolidation grouting operations.
